01 Pete isx engine brake

[Jchism3406]

I have a 2001 Peterbilt with isx and I was wondering if the engine brake rockers touch in the inside of the head

go to https://quickserve.cummins.com and register your engine ser# (ESN#) ... it is free and all drawings, manuals, repair procedures, etc... are all there.

Yeah I don’t think that’s going to help me

I know #5 and #6 on my 2006 cm870 exhaust rockers would hit/touch the inside of the head. I dont know anything about the cm570 you're probably dealing with.

I’m not sure how to include videos I’m using an iPhone

Post your video to YouTube or another video hosting site then post a link here.

If they are making a harsh rattle/tapping noise at idle or just after jakes are disengaged then you probably have heavily worn detent pockets in your rocker shafts.
